Sarah lay on her back, as the person fucking her came inside her, filling her cunt with cum, causing what was left of her mind to spark with pleasure. She would have reflected on how she came to be in this situation, but that was a bit beyond the brainless, latex, fuckdoll that she had become.
It had all started a few weeks ago when her boyfriend had left to go work overseas with his collaborators in experimental research. Before he left, he had given her a small black and silver box, containing a pair of latex bra and panties. She was intrigued as she had previously expressed her desire to wear them, and this would mean she could get used to wearing them before he came home.
Having gotten back from dropping him at the airport, she got home, showered, and slipped on the latex wear, taking a few pics to send to her boyfriend to tease him. She loved the ways they hugged her body, almost like a second skin.
After spending the day in latex, with the occasional touching and stroking of herself, she changed for bed, wiping some moisture off her body from where the latex had sat.
The following week she was busy with work, but was able to leave early on the Friday. Getting home, she showered and was about to get changed into comfy clothes, when she came across the latex undies. Slipping them on, she marvelled at just how well they fit her compared to the last time.
Grabbing her phone, she began taking a few more pics for her boyfriend to add to the ones she'd already sent him. Half an hour later, phone forgotten, she was on her back, gasping as her fingers worked their way deeper and deeper into her cunt, while her other hand pinched her nipples. As her orgasm rocked through her, she had a vision of herself coated in latex, before she passed out.
Waking up later, she slipped out of the latex, and again was puzzled at the presence of liquid on her skin from the latex. Shrugging, she put the undies away, changed for bed and went back to bed. That night, her sleep was troubled by images and thoughts of latex coated bodies and her boyfriend fucking her as she lay motionless beneath him.
The next morning she woke, showered, wrapped herself in her robe and sipped at her coffee. Walking back into her bedroom, she caught sight of her latex undies sitting on her bed, causing her to moan slightly and her cunt to moisten at her dreams from the night before.
Dropping her robe to the floor, she picked up her undies and was curious at the strange liquid on the inside. She shrugged, and slipped them on anyway, again surprised at just how well they fit her body.
Checking herself in the mirror, she was a little surprised to see that apparently the undies had changed slightly, seeming to have covered more of her body. Making a mental note to ask her boyfriend about it when he called her next, she started doing some chores around the house.
Around midday her boyfriend called, his deep voice immediately putting her at ease and making her wish that he was home and that she could hug and kiss him once more. As they talked, her hand slowly made its way down her body to slowly stroke herself through the latex. Her boyfriend was saying something to her, but she wasn't really aware of what he was saying. Something about latex, and fuckdolls, and how she needed to relax and not think about things so much. As he talked, her responses became breathier and more akin to moans than words, her mind filling with the idea of herself being covered in latex and fucked for hours until she came loudly, moaning her boyfriends name.
She came to later, stretching as her body complained about her passing out on the couch. Stripping off her latex undies revealed the same liquid on her skin from the last few times she'd worn them, which she began rubbing into her skin. She didn't really know why. Something about it being important to do every so often.
